The site, a certain mass of gas occupies a Colume of 790 cm³ find the temperature at which the gas occupies 1000 cm3 and has a Pressure of 726 mmHg.

Abeaker with 2.00×102 ml of an acetic acid buffer with a ph of 5.000 is sitting on a benchtop. the total molarity of acid and conjugate base in this buffer is 0.100 m. a student adds 4.70 ml of a 0.360 m hcl solution to the beaker. how much will the ph change? the pka of acetic acid is 4.740.
